Injection site rotation is a recordkeeping problem as much as a technique problem. The official labels for Ozempic, Wegovy, Mounjaro, and Zepbound all describe subcutaneous injection and use product-specific injection-region language. Ozempic and Wegovy list the abdomen, thigh, and upper arm; Mounjaro and Zepbound list the abdomen or thigh for the patient and the back of the upper arm when another person gives the injection. They also use product-specific rotation language, which is why this guide stays close to the label and avoids choosing a site for you. (Ozempic PI; Wegovy PI; Mounjaro PI; Zepbound PI)
For the full pillar overview, start with the GLP-1 injection guide.
What rotation means in the labels
Rotation is not a Dosley-made rule. The Ozempic label says to use a different injection site each week when injecting in the same body region. The Wegovy label says to rotate injection sites with each dose. The Mounjaro and Zepbound labels also describe weekly subcutaneous injection and tell patients to rotate injection sites. (Ozempic PI; Wegovy PI; Mounjaro PI; Zepbound PI)
Those label statements are general product instructions. Your clinician, pharmacist, and the current Instructions for Use are still the source for how the routine applies to the product in your hand.
Region, side, and exact spot are different notes
People often remember only the broad body region. A more useful log separates three details:
- region: abdomen, thigh, or upper arm for Ozempic and Wegovy. Mounjaro and Zepbound list only the abdomen or thigh when you inject yourself, and the back of the upper arm when someone else does it, so note who gave the injection (Ozempic PI; Wegovy PI; Mounjaro PI; Zepbound PI)
- side: left, right, or another simple descriptor
- exact note: a short reminder such as “lower left abdomen” or “right thigh”
The goal is not to create a medical map. The goal is to avoid relying on memory when weekly events start to blur together.
What not to infer from a rotation log
A log shows where and when you injected and what you noticed afterward. It cannot tell you which site is best or explain a symptom. What it is good at is catching what memory misses. If the notes show the same exact spot week after week, that is a specific thing to raise at your next appointment.
If a pattern worries you, bring the log to a healthcare provider or pharmacist. Clear notes make that conversation easier without turning the app into a clinician.
A simple rotation note format
Keep each entry plain:
- Date and time.
- Medication name.
- Dose as prescribed.
- Body region and side.
- Pen or device note.
- Observation to discuss later, if any.

That format also connects to other practical guides. Travel can disrupt what you remember, so see Traveling with GLP-1 pens for packing and storage recordkeeping. For the broader tracking system, see What to track during a GLP-1 routine.
